The Shadowserver Foundation

Accessible Remote Desktop Protocol Scanning Project

If you are looking at this page, then more than likely, you noticed a scan coming from this server across your network and/or poking at the RDP (Remote Desktop Protocol) service on port 3389/tcp.

The Shadowserver Foundation is currently undertaking a project to search for publicly accessible devices that have the RDP service running. The goal of this project is to identify openly accessible systems that have the RDP service running and report them back to the network owners for notification.

This service has the possibility of disclosing sensitive information or unknowningly providing remote access to the system if configured improperly. If at all possible, we would like to see these services made un-available to miscreants that would misuse these resources.

Servers that are configured this way have been incorporated into our reports and are being reported on a daily basis.

Methodology

We are querying all computers with routable IPv4 addresses that are not firewalled from the internet on port 3389/tcp with an RDP negotiation request and capturing the response. If a host replies affermatively, we follow that query up with an attempt to fetch the client's SSL certificate. We intend no harm, but if we are causing problems, please contact us at: dnsscan [at] shadowserver [dot] org.

If you would like to test your own device to see if it has RDP accessible, try the nmap command: "nmap -v --script=ssl-cert -p 3389 [IP]"

Whitelisting

To be removed from this set of scanning you will need to send an email to dnsscan [at] shadowserver [dot] org with the specific CIDR's that you would like to have removed. You will have to be the verifiable owner of these CIDR's and be able to prove that fact. Any address space that is whitelisted will be publicly available here: https://rdpscan.shadowserver.org/exclude.html
